Sarcolemma of skeletal muscle prepared by a quick-freeze deep-etch method also shows the basement membrane (lamina externa, labeled here as the basal lamina) associated with the muscle fiber. This method reveals a basement membrane composed of a meshwork of fibers, some of which contact the cell membrane. The larger fibrils outside of the lamina externa (to the far lower right of the image) are composed of collagen.
